COMPOSITION Iii OR FILLING JOINTS IN METALLIC BODIES.

To all whom it may concern:

Be it known that I, JOHN D. \VHITE, a

' subject of the King of England, residing at Toronto, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Composi- 'tions for. Filling Joints in Metallic Bodies,

of which the following is a specification.

This invention relates to the art of joining metallic sections, and particularly to a composition to be used at the joint. of the sections to prevent the passage of water therethrough 'or for other purposes which .will be later described.

vent the entrance of water into or the passage of water through the joint.

' Still another object is the provision of a composition which may be very readily made and which will be very cheap.

In the manufacture of metallic vessels or other articles made up of a number of pieces, it is necessary that the pieces shall be joined toeach other by interlocking the seams, and that these seams should be closed by solder so as to prevent liquid from getting into the seams and also prevent the leakage of liquid through the seams. The cost of solder is relatively high, and the application of solder to the seams of cans, kettles and other vessels relatively troublesome. It is for the purpose of doing away with this necessity of using solder that I. have provided the composition which will now be described. W 1

In order to form this composition 1 take equal parts of finelyground whiting and alum with sufficient varnish or other like vehicle added to give the material the consistency of liquid, it being understood, of course, that the finely ground whitln'g and finely ground alum are to be thoroughly mixed with each other and with the varnish so as to obtain a liquid or semi-liq- Specification of LettersPatent.

uid of uniform consistency. In the makmg up of the vessel this liquid is disposed within the seams, that is, upon the facesof the metal portions which are interlocked with each other, and then the vessel is made up in the usual manner. When the vessel is already-made up and the seams locked, my improved composition may also be applied thereto and will perform the same purpose as when it is locked into the seams by forcing it into or otherwise applying it over i and around the seams. ever, aluminum bronze powder should be mixed with the alum, whiting and varnish so as to give it the appearance .of solder. It is to be understood that aluminum bronze is only used forthe sake of appearance and has no effect otherwise upon the action of the composition.

:W'herd the composition is to be applied to the seams of vessels or other articles, it

is in more or less liquid form, but I have found that it may also be put up in the form of apaste, in which case less varnish is used so that the mass is less liquid. In this condition it may be readily applied with the finger to the exterior of the joints of metal parts, as for instance, the joints in eaves gutters, troughs, metallic'pipe, etc, and may also be used at the joint or'junction of electric wires. Thus it may be used at the j unction of intertwisted electric wires; According to the underwriters rules joined wires must be soldered, taped twice and then painted. I use my composition in place of solder, thoroughly covering the intertwisted wires with the composition and then applying the tape thereto. I have found in actual use that this mannerof covering the joints of electric wires is thoroughly effective and In this case, howthat the composition in every respect takes the place of solder.

The composition may be used upon tin, copper, galvanized iron, brass or sheet aluminum. lVherever there is a scam the seam may be filled or closed by means of this composition. It is wellat this time to call ticular attention to the fact that there are very few vessels to-day made up of sections of aluminum, and this is for the reason that found that'would adhere to aluminum. In actual test, however, I have found that the composition I have described will very closely adhere to aluminum and W111 fill up .there has never heretofore been a substance the seams sothat there is no possible chance of leakage of water therethrough. -My improved composition is not for the purpose of holding two pieces of metal in conjunction with each other. It has no eifect in this regard. It is purely for the purpose of filling the space, joint or seam between two metallic sections so as to preventthe passage of liquids. 1

While I have heretofore stated that I preferred to use a compositionconsisting of alum and whiting-powdered borax could be used in place of the whiting and also powdered barytes, or what is known as heavy spar.

There is no chemical action between the powdered whiting, barytes or borax, whichever is used, and the alum, if mixed in dry form, unless the powders are mixed with water, but this would simply form a hard mass which would be of no value for my purpose. By mixing finely powdered whiting and alum with varnish, the varnish decreases the brittleness of the dried mass, adds to its powerof adhesion and increases the resistance of the material. One reason for using whiting, barytes, and other inertmaterials is that they are insoluble in water. I have found in practical experience, however, that whiting and alum have such qualities that when varnish is added thereto a composition is-formed with great adhesive power and also hardening quality, so that when this composition is hard, liquids cannot penetrate. Alum alone would be too hard and I find cannot be used practically. Whiting serves to render the composition less hard, and further, to cause it to solidify in a short time when mixed with a liquid such as varnish, it of course being understood that this solidification takes place in the presence of air. Thus the composition may be made up in the form of a paste and kept in this pasty consistency provided it is kept from the air. 'In,a short time, however, if air is allowed to Contact with it, it will solidify and become very hard.

Having described the invention, what I claim is:

1. A material for closing joints orseams between metallic parts containing equal quantities of finely powdered whiting, finely powdered alum, and varnish.

2. A material for closing joints or seams between metallic parts containing equal quantities of finely powdered alum, and whiting, varnish, and finely powdered aluminum.

3. A material for closing joints or seams between metallic parts ntaining equal parts of finely powdered aiiim and finely powdered inert insoluble filling material, and varnish.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses.
